Syntax

public static class MemoryMappedFileExtensions

Methods

CreateDirectAccessor(MemoryMappedFile, long, long, MemoryMappedFileAccess)

Creates direct accessor to the virtual memory associated with the memory-mapped file.

Declaration

public static MemoryMappedDirectAccessor CreateDirectAccessor(this MemoryMappedFile file, long offset = 0, long size = 0, MemoryMappedFileAccess access = MemoryMappedFileAccess.ReadWrite)

Parameters

Type	Name	Description
MemoryMappedFile	file	The memory-mapped file.
long	offset	The byte at which to start the view.
long	size	The size of the view. Specify 0 (zero) to create a view that starts at offset and ends approximately at the end of the memory-mapped file.
MemoryMappedFileAccess	access	the type of access allowed to the memory-mapped file.

Returns

Type	Description
MemoryMappedDirectAccessor	The direct accessor.

Exceptions

Type	Condition
ArgumentOutOfRangeException	offset or size is less than zero.

CreateMemoryAccessor(MemoryMappedFile, long, int, MemoryMappedFileAccess)

Creates memory accessor to the virtual memory associated with the memory-mapped file.

Declaration

[CLSCompliant(false)]
public static IMappedMemory CreateMemoryAccessor(this MemoryMappedFile file, long offset = 0, int size = 0, MemoryMappedFileAccess access = MemoryMappedFileAccess.ReadWrite)

Parameters

Type	Name	Description
MemoryMappedFile	file	The memory-mapped file.
long	offset	The byte at which to start the view.
int	size	The size of the view. Specify 0 (zero) to create a view that starts at offset and ends approximately at the end of the memory-mapped file.
MemoryMappedFileAccess	access	the type of access allowed to the memory-mapped file.

Returns

Type	Description
IMappedMemory	The direct accessor.

Remarks

This method is suitable if you need to represent memory-mapped file segment as Memory<T>.

Exceptions

Type	Condition
ArgumentOutOfRangeException	offset or size is less than zero.
